To all 1x1/'hom' it TV1/@Ly con-cern: l

Be it known .that we, ROBERT HADDEN and CHARLES SENN', citizensv of the United States, and residentsiof Atlantic' City, 4county'of Atlantic, .and 'State' of New Jersey, have inventedacertain new andu'seful Improvement in NoneSiphon Traps, of which the liollowing is a description.

Theobjectrwe have in view is thevprodictionof `a non-Siphon trap. yThis trap may be` used in connection withxany type of fixture-- such-as bathtubs, sinks, andwashstandsbut is particularly applicable Ito bath-tubs 'fand for use inbath-rooms.

lFur-ther objects f are to produce a`- trap vwhichcan be constructedfcheaply, whichv, ill not jossiblyqsiphon,` and which'willbe ofA =minimum'height, so that, ifvdesired, in use yin connection'with bath-tubs it -may be' vplaced':above thfe iloor and-,yet under 4the bath-tub.

Further objects areftheproduction of a trapwhich may be accessible forfrepairs and for. the purpose ofr removing vobjects which may accidentallyffall into it; and a-'still furlther object is the-production vof a trap which.

theposition of' the'inlet and outlet pipes may be adjusted to 'connect with itheplumbing.

y'We attain'these objects bymeansfof the mechanism illustrated in the accompanying drawings,.in which-` Figure 1- isanmelevation of a bath-tub,

showing attached thereto a trap embodyingl our invention. Fig. 2 is an enlarged `sectional view taken on the lines 2 2 of Fig. 3. Fig. 3 is a bottom plan view of' the trap. Fig. 4 is a detail view o1 the trap used in connection with a bath-tub and placed. to oner side of the tub and connected to both overflow and waste pipes.

In all ofthe views like parts are designated by the same reference characters.

ln carrying out our invention we provide "two trap-bod'ies'l 2,. secured together and constituting a water-chamber. These two trap-bodies are preferably essentially alike. They may be made of any material of which traps are commonly made, suchas copper, lead, or other metal. -Each body is in the form of an enlarged chamberS, having a flat base 4 and a tapering or restricted neck '5. Connecting the body on the side and adjacent to the base is the inlet or outlet passage 6 in the form of a nipple. Each nipple is providedl with means for' attachment tothe inlet and eXit pipes 7 and `9,y respectively.

ablesize is permissible.

'will be .in proper position. 'permits this to be done,land the shape of the bodies allows of a coupling of moderate size,

' coupling 10 isslipped over the neck.

. By leading off the lpipes from the side vthe height of the trap is restricted, and it is possible -to yplace it below an ordinary bath-tub andat the sante timeabove the `floor. The neck 5 'of each body is considerably smaller Vthan the chamber 3.

The two necks ofv the two bodies which constitute the trap are connected together -by a'suitable'coupling. so thata complete trap will be formed. lB'ytapering they bodies lto the' shapeof necks aV coupling of manage- The coupling `is vpreferably made so thatnone body .may be adjusted in relation to the other, so that the 'lead-oT-and inlet pipes may be lproperly lolcated to connect'with the plumbing.

This will-bedone by suitably adjusting one body infrelation to the 'other so-that thenipples The coupling which may Ibe .adjusted by ordinary tools. 4Avery satisfactory form of coupling is shown inthe drawings. The neck of one of the bodies is provided with threads, to which is attached a washer 9. The threads which connect the Washer and the neck are preferably small thre'ads, andl the washer maybe further at- "tached to the neck by soldering. The washer `9 is provided with a male thread which en- -gages with a flange-coupling 10, which has an engaging female thread. This coupling en- .gages 'with a ledge or shoulder 11, formed *upon the neck 5.on the upper `body l.

two bodies are adjusted the proper rela' tion so that the lead-off pipes will lead in the proper direction. 'The coupling 10 is so shaped as to be engagedy by a wrench. (See Fig. l.) Thev coupling l0 will ordinarily be designed to be of ysuch a size thatit may be adjusted by an ordinary wrench. The small size of the coupling is made possible by the shape ofthe bodies.

The lower body 2 is preferably provided IOO IIO

with a manhole or vent 13, which may be closed. by a plug, a screw-plug being illustrated. This manhole will be lower than the inlet-pipe. Therefore objects falling into the trap will enter the chamber and may be readily removed. This is particularly advantageous in removing objects which may accidentally fall into the fixture without the necessity of calling in the services of a plumber.

As shown in Fig. 4, the manhole or vent 13 is arranged in the upper body. This permits the trap to rest upon the loor, and the inside may be reached Jfor the removal of foreign objects. In Fig. 4 the trap is shown in connection with a bath-tub and is connected to both the overilow and waste pipes. it is to be understood that the trap is not limited Jfor use in connection with bath-tubs, as it may be employed in connection with any fixture.` Ordinarily in connection with sinks, washstands, &c., the trap will be set as shown in Fig. 1 with the vent k3 in the lower body.

In operation the body 2 and the neck of the body 1 will be filled with water to the4 level indicated at 14. When the fixture is emptying, the water will iow down the pipe 6, through the body 2 to the body 1, and through the pipe 8. Should the column of water in the pipe 8 be su'liiciently long to produce a vacuum in the trap when the iixture is empty, the trap will not empty and the seal will not be broken. This is made possible owing to the size of the chambers 3 within the bodies, which provides a suilicient bulk of water to prevent both of the bodies being emptied by the suction action of the pipe 8. The location of the lead-0H pipe at the side also tends to prevent siphoning. Were it on the top, a portion of the water in the trap would be blown upwardby the airpressure and would enter the lead-ofi pipe. By having the latter on the side this will not occur.

In use it is found that the seal cannot possibly be broken by any siphoning action ol the draw-ofi pipe.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A non-Siphon trap having two waterchambers, which are connected together by a tapering neck, and having pipes, said pipes leading oil and on the sides oi' the chambers, whereby a long seal will be produced, with a low trap.

2. A non-Siphon trap having two bodies, each with a lead-pipe, the said bodies each having a restricted neck, and means for connecting the two necks, so as to permit the adjustment of one body in relation to the other and allow the lead-pipes to be properly located to connect with the plumbing.

3. A non-Siphon trap having twov bodies, each with a lead-pipe, 'the said bodies each having a restricted neck, and a coupling connecting the two necks.

4. A non-Siphon trap having two bodies, each with a lead-pipe, the said bodies cach having a restricted neck, and an adjustable coupling connecting the two bodies, the said coupling permitting adjustment of the bodies y.to suit the location of the plumbing.

5. A non siphon trap comprising two bodies each of a like coniiguration, cach having an enlarged portion and a restricted neck, and a coupling connecting the two necks.

6. A non e Siphon trap comprising two bodies, each of a like coniiguration, each having an enlarged portion with a nipple for a lead-pipe on the side, and a restricted neck, and a coupling connecting the two necks.
